摘要：

Poly(vinyl borate), PVBO and lithium derivative of PVBO can be prepared by homogeneous esterification of PVA with boric acid in non-aqueous medium in the presence of a catalyst C2H5ONO2-DMSO. The compounds were characterised by IR and H-1 NMR spectra. Conductivities were determined from 30 to 90 degrees C in solid state. The compounds so formed showed ionic conductivity and their conductivities were dependent on frequencies used. The addition of Li+ ion increases the ionic conductivity of PVBO dramatically. The total ionic transport number and activation energy of the polymers were also determined. (c) 2007 Elsevier B.V. All rights reserved.
